Detailed Description

template<class typeparams>
class smp::cost_evaluator_time< typeparams >

The cost evaluator class based on the trajectory execution time.

This class computes the cost of a trajectory according to the time it takes to execute that particular trajectory.

template<class typeparams >

int smp::cost_evaluator_time< typeparams >::ce_update_edge_cost

(

edge_t *

edge_in

)

[virtual]

Update function for edge cost modification.

This function is called by the planner whenever the cost associated with an edge is changed by the optimizing (incremental) planning algorithm.

Parameters:

edge_in

A pointer to the edge with modified cost.

Returns:

Return 1 if success, a non-positive value to indiacate error.

Implements smp::cost_evaluator_base< typeparams >.

template<class typeparams >

int smp::cost_evaluator_time< typeparams >::ce_update_vertex_cost

(

vertex_t *

vertex_in

)

[virtual]

Update function for vertex cost modification.

This function is called by the planner whenever a the cost associated with a vertex is changed by the optimizing (incremental) planning algorithm.

Parameters:

vertex_in

A pointer to the vertex with modified cost.

Returns:

Return 1 if success, a non-positive value to indiacate error.

Implements smp::cost_evaluator_base< typeparams >.

template<class typeparams >

double smp::cost_evaluator_time< typeparams >::evaluate_cost_trajectory	(	state_t *	state_initial_in,
		trajectory_t *	trajectory_in,
		state_t *	state_final_in = 0
	)		[virtual]

Evaluates the cost of a trajectory.

This function returns the cost of a given trajectory that starts from state_initial_in and reaches state_final_in. Sometimes the final state is embedded in the trajectory itself, in which case state_final_in argument can be set to NULL.

Parameters:

state_initial_in	Initial state that the trajectory starts from
trajectory_in	Trajectory
state_final_in	Final state that the trajectory reaches

Returns:

Returns 1 for success, and a non-positive number to indicate error.

Implements smp::cost_evaluator_base< typeparams >.
